The symposium, reflecting on the relation between theory and evidence in semantics, honors David Dowty's many contributions.

David Dowty has contributed extensively and creatively to many areas in grammatical theory for over thirty years, including especially tense and temporal reference; inherent verbal aspect (Aktionsarten); categorial grammar, Montague grammar, and phrase-structure grammars; semantic compositionality; quantificational adverbials; the theory of grammatical relations and relation-changing rules, the logical status of thematic roles, and the relation between grammatical licensing and surface realisation. This symposium honors him and these many contributions.
